##### Lumens :

- The lumen is the unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time, in the International System of Units.
- Then, the symbol of lumens is
**lm**.

##### Millicandela :

- It is the One thousandth ( 10
^{–}^{3}) of a candela. - Then, the symbol of millicandela is
**mcd.**

##### Lumens to Millicandela :

- The lumen is the unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time, in the International System of Units.
- The candela (symbol: cd) is the SI base unit of luminous intensity.
- It is the power emitted by a light source in a particular direction, then weighted by the luminosity function.
- The SI prefix “milli” represents a factor of 10
^{-3}, or in exponential notation, 1E-3. - So, 1 millicandela = 10
^{-3}candelas.

##### Formula :

- The formula used to calculate the following calculator lumens to millicandela is given below.
- The apex angle in degrees value should be in assingment operator.
- So, the apex angle in degrees = Math.PI/180.
- Then, the calculation formula = 1000 * Enter Luminous flex in lumens / ( 2 * Math.PI * ( 1 – Math.cos ( The apex angle in degrees / 2 ))).
- Besides the formula this calculator works.

##### How to Calculate ?

- First, Enter the Luminous flex in lumens.
- Second, Enter the Apex angle in degrees.
- Click “Calculate” to get the result and then if you want to clear values Click “Reset” in addition to clear the values.
- Finally, follow these steps to get the results.
- Then you will get as a Luminous intensity result in millicandela.
